Much like the gremlin Gizmo, only in human form. A spoiled child. The child is cute and cuddly until you piss them off by telling them the dreaded word "No" then they turn into a hideous little monster.

Derogatory term used to describe someone of Japanese descent. Derived from the fact that these people are always gizmo-ing about and making crazy devices to do all sorts of perverse things that only the Japanese could think of.

Try calling your Japanese friend a gizmo, and you'll see just how right it feels.

Watch any popular Japanese television show for excellent examples of Gizmos doing what they do best.
